P-wave Duration and Dispersion in Lone Obesity

OBJECTIVE To assess P-wave duration and dispersion (PD) in morbidly obese young subjects who do not have co-associated atrial fibrillation (AF) risk factors, such as hypertension, diabetes, atrial enlargement and diastolic dysfunction. STUDY DESIGN An observational cross-sectional study. PLACE AND DURATION OF STUDY Bolu Abant Izzet Baysal University Medical Faculty, Turkey; and the study was conducted between October 2017 and June 2018. METHODOLOGY P-wave duration and dispersions were determined on 12-lead surface ECG in 47 morbidly obese and 44 healthy weight subjects, aged between 21-40 years. Above mentioned risk factors were studied. The correlation between BMI, PD and Pmax were investigated by Pearson correlation analysis. Results: Average body mass index (BMI) of obese and control groups were 42.3 (8.5) vs. 19.5 (1.5) (P
